How to force websites to save passwords to iCloud Keychain in OS X Mavericks

Note: This feature does not appear to be available as of OS X Yosemite

Not all websites just let you save passwords to iCloud Keychain. Whether for privacy or security reasons, or simple technical misconfiguration, sometimes your best efforts to stay in sync across your Apple devices will be stymied... at least at first. Luckily, Safari can often let you save passwords even if the website itself tries to stop you. Here's how to do it in OS X Mavericks.

How to force save logins to iCloud Keychain in OS X Mavericks

Launch Safari from the desktop of your Mac running OS X Mavericks.

In the top menu bar, click on Safari and then Preferences.

In the menu, click on Passwords.

Under your list of passwords, check the box for Allow AutoFill even for websites that request passwords not to be saved.

That's it! Safari and iCloud Keychain should now save and fill in logins even for sites that have requested you not store them!
